Feeling the Heat? Grab a Glass of Milk

If you’re currently melting in the nationwide heat wave and reaching for another bottle of water, you might want to reconsider.

A doctor in the U.K. is making waves online for suggesting that milk—good old-fashioned cow juice—is actually a better hydrator than water when the temperature climbs. That’s right, your childhood beverage of choice might just be your best defense against dehydration.

So what makes milk so magical in the heat? First off, it’s about 87% water. But what gives it an edge is everything else in it.

The sugar, protein, and fat slow down digestion, which means your body holds onto the fluids longer. Translation: you stay hydrated longer without constantly chugging fluids like a camel at a spa.

Milk also packs a sneaky punch of sodium, which helps your body retain water . . . basically functioning like a natural sports drink. Electrolytes? Check. Hydration? Check. Weird looks from your friends when you’re chugging milk in 95-degree heat? Also check.

But don’t worry, vegans and dairy-intolerant folks aren’t out of luck. The doc says soy milk is a solid alternative with similar hydration benefits. Just skip the vanilla almond-coconut-oat extravaganza if hydration is your goal . . . those might not have the same water-retention magic.

While you might not see athletes slamming milk instead of Gatorade anytime soon, the science adds up. So next time you’re overheating and reaching for a sports drink, consider moo-ving over to the dairy section instead.
